Mod_tile is a system to serve raster tiles for example to use within a slippy map. It provides a dynamic combination of efficient caching and on the fly rendering. Due to its dynamic rendering, only a small fraction of overall tiles need to be kept on disk, reducing the resources required. At the same time, its caching strategy allows for a high performance serving and can support several thousand requests per second.

This package contains the renderd daemon that creates "metatiles" for map tile requests issued by mod_tile using the mapnik library.
